Rails 2 way:
There was :as option in routes. Which rename routes.
Assume that you have next in routes.rb
resources :blogs # /blogs
If you want to rename it from urls perspective you can:
resources :blogs, :as => ‘posts’ # /posts
But, in rails 3 this doesnt work.
As workaround I can propose next:
resources :posts, :as => 'blogs', :controller => 'Blogs'
I start playing with rails 3 and mongo. Found lot of articles on this theme, but only some steps works for me. Most useful is post by Nicola Racco.
I’ve created simple web app with authentication and attachments photo/video.
As js framework I use jQuery 1.4.2. For integration use smth like:
http://github.com/CodeOfficer/jquery-helpers-for-rails3
I use http://gist.github.com/399682, that found somewhere on github.
For authentication: devise
for attachements: carrierwave
ORM: mongoid
Paginations: Mongoid paginate + will_paginate for views
Here is my steps:
Install rails 3 beta 3
gem install rails --preCreating app
rails myproject --skip-activerecordensure that in config/application.rb
require 'action_controller/railtie'
require 'action_mailer/railtie'
require 'active_resource/railtie'
require 'rails/test_unit/railtie'
instead of:
require 'rails/all'As ORM I choose Mongoid. Beacuse in devise 1.1.rc1 orm adapter only for mongoid and there are no adapter for mongo_mapper
gem "mongoid", "2.0.0.beta4"Now lets start implement app logic
Authentication:
gem 'devise', :git => 'git://github.com/plataformatec/devise.git'I’ve installed device 1.1.rc1,
bundle installNext install devise
rails generate devise_install
Rails will generate the file “config/initializers/devise.rb”, responsable of the Devise initialization. Opening the file you’ll see several options that you can configure as you like to customize the framework behavior. In this article the task is to make Devise to work with Mongoid, so we don’t care of these options. Let’s change the line:
require 'devise/orm/active_record'
in:
require 'devise/orm/mongoid'
Next steps following devise docs:
class User
include Mongoid::Document
include Mongoid::Timestamps
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable#, :validatable
has_many_related :posts
end
Pagination:
Post.all.paginate(:page => params[:page], :per_page => 10)
for views simply use will_paginate
Attachements:
http://github.com/jnicklas/carrierwave
Uploader placed in app/uploaders
lass PhotoUploader < CarrierWave::Uploader::Base
include CarrierWave::Compatibility::Paperclip
include CarrierWave::RMagick
storage :file
def store_dir
":rails_root/public/photos"
end
def paperclip_path
":rails_root/public/photos/:style/:basename.:extension"
end
version :thumb do
process :resize_to_fit => [800,600]
end
end
Model
require 'carrierwave/orm/mongoid' class Photo include Mongoid::Document include Mongoid::Timestamps field :title, :type => String field :permalink, :type => String field :content, :type => String # field :hit, :type => Integer, :default => 0 field :photo, :type => String field :photo_file_name, :type => String belongs_to_related :map mount_uploader :photo, PhotoUploader, :mount_on => :photo_file_name end
Controller
class PhotosController < ApplicationController
def create
photo = Photo.create(params[:photo])
redirect_to(:back)
end
And views:
<% form_tag videos_path, {:multipart => true} do %>
<p>
<label>Photo</label>
<%= file_field_tag 'video[video]' %>
</p>
<%=submit_tag 'Upload'%>
<% end %>
When having lot of updates ( ~ 7983)
Memory used by daemon permanently growth upto 800Mb
THe problem is next
When saving record without validation save(false) max mem usage was 161 Mb
But there are no validations for this object
When I go through source code. Found that this issue because of valid? method.
Going more deeply I found that issue with new_record?
def new_record?
@new_record
end
Strange )

“IE6 вышел в 2001 году, с тех пор успели разбомбить ВТЦ, захватить Афганистан, Ирак, выбрать по два раза Жору Куста с дядей Вовой, и по одному разу Обаму с Медведевым. За этот же срок прокатились всякие оранжевые революции, придумали Ладу Калину и Приору, телефоны проделали путь от 3310 до IPhone’ов и Nexus One, опять таки за это же время появились и достигли сегодняшних высот facebook, twitter, vkontakte и ещё уйма всего. А интернет технологии что, на месте что ли по-вашему стоят? Хороша ложка к обеду, IE6 своё давно отжил.” — С ХабраХабра про Internet Explorer 6 (via ld100)
I’ve got couple of screencasts from some conferences. At some moment I want to listen it going to work. So I need play it in background but regular control will stop screencast after locking iPhone or exiting iPod.
But next trick is working. Run screencast then exit the iPod app and it will be stopped. Next you should just push play button on garniture (on headphones) and screencast plays in background!
Ubuntu 8.04 packages has 6.3.7 but i need at least 6.3.8.
I decide to build it from source. And got next from shell it works, also it works from Rails ./script/console. But it doesnt work from Passenger.
Solution
When building from sources
Dont forget configure with —disable-openmp
and after make install
run sudo ldconfig
